SLMs key to optical information processing, displays

The importance of spatial light modulators (SLMs), devices that impose spatial information patterns on optical beams, lies in their being the critical elements of optical information processing, communication, and display systems. Thus SLMs, or light valves, are the key elements in most display applications—from wristwatches and miniature liquid crystal TV monitors, through flat panel displays to high brightness, large screen projectors for theaters, teleconferencing, and flight simulation applications.
